Dimple grinding offers a fast and reliable mechanical method of pre-thinning to near electron transparency (in some cases to electron transparency) greatly reducing ion milling times and uneven thinning. Dimple grinding also offers a means of producing quality TEM specimens having a large central area only a few microns thick surrounded by a robust outer rim. This eliminates special handling techniques for fragile specimens.
Scanning function for easy determination of parameters LectroPol-5 is equipped with a unique scanning function. The sample is placed on the polishing table and a pre-defined voltage range is scanned to determine the current density curve. This curve is used to define the correct voltage for both polishing and etching.
